QuantActions Flutter Plugin #
The QuantActions plugin for Flutter enables a developer to add all the QuantActions functionalities to a Flutter app. This includes:

Automatic data collection
Access processed metrics and insights from the Tap Intelligence Engine (TIE)
Enabling device communication
Subscribe to different cohorts

The QuantActions plugin for Flutter can be set up with a few easy steps. For a practical example, please see the example directory.
Important for the plugin to be functional you will need an api_key from QuantActions. If you have not yet received your api_key please contact us.
Initial (Flutter) setup #
Add the dependency to your pubspec.yaml file:
dependencies:
quantactions_flutter_plugin: ^0.1.8
copied to clipboard
Initial (Android) setup #
We recommend using Android Gradle Plugin (AGP) 8.5+ and Kotlin 2.0+.
In your add the github maven repo containing the QuantActions Android SDK,
the repo and the package are public but you still need a github account to access them, it is best to use a personal access token for this:
allprojects {
repositories {
...
maven {
name = "GitHubPackages"
url = uri("https://maven.pkg.github.com/QuantActions/quantactions-android-sdk")
credentials {
username = '...'
password = '...'
}
}
}
}

Recommended: You might want to add some Android specific customization (see below and QuantaActions Android SDK to do so you will have to add also the direct dependencies to your app/build.gradle file
implementation 'com.quantactions:quantactions-android-sdk:1.1.0-rc04'
copied to clipboard
These steps suffice to correctly integrate the plugin into the app (Android side) but continue reading the QuantaActions Android SDK documentations for more information on how to setup the android permissions necessary to start the data collection.
Initial (iOS) setup #
For iOS you can follow the instructions in the QuantaActions iOS SDK documentation in particular you can start from adding your api_key.
Note that you can skip the installation step of the native SDk as this is already done by the plugin.
You will se in the native iOS documentation that you will need to add a custom keyboard extension that will be responsible to collect the data.
After the iOS setup is done you will need to add to you app Podfile the following lines to make sure that the QuantActions SDK is correctly linked to the keyboard extension.
(Replace NameOfYourKeyboardExtension with the name of your keyboard extension)
target 'Runner' do
use_frameworks!
use_modular_headers!

flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))

target 'NameOfYourKeyboardExtension' do
inherit! :search_paths
end

end

2. Adding QA functionality to an app #
The whole QA functionality can be accessed everywhere in the code by the singleton QA that can be
instantiate like this.
import 'package:quantactions_flutter_plugin/quantactions_flutter_plugin.dart';
final qa = QAFlutterPlugin();
copied to clipboard
Before using any functionality, the QA singleton needs to be initialized. To do so you will need an api_key provided by QuantActions. If you have not yet received your api_key please contact us.
We recommend the use of dotenv to handle the API key in Flutter.
Create a .env file in the root of your project and add the following:
api_key=<you_api_key>
copied to clipboard
In your main.dart file you can retrieve the api key:
import 'package:flutter_dotenv/flutter_dotenv.dart';

void main() async {
await dotenv.load(fileName: ".env");
static final String tempApiKey = dotenv.env['api_key'] ?? '';
runApp(MyApp());
}
copied to clipboard
then you can access it in the code and initialize the QuantActions plugin.
qa.init(
api_key: dotenv.env['api_key'],
age: 1991,
gender: Gender.other,
selfDeclaredHealthy: true
);
copied to clipboard
3. Sign-up to a cohort #
To track a device it is necessary to subscribe the device to a cohort. To do so, simply use the cohortId provided by QA.
qa.subscribe(subscriptionIdOrCohortId: '');
copied to clipboard
When subscribing the device using a cohortId, the device gets automatically assigned a subscriptionId, to retrieve this id one case use the following code.
final List<Subscription> subscriptions = await _qa.getSubscriptions();
copied to clipboard
Note that each user can be subscribed to multiple cohorts at the same time

4. Multiple devices (Android only for now) #
It is possible to link multiple devices to the same user by providing identityId and password during the initialization of the SDK. This way the SDK will be able to link the data from the different devices to the same user.
In the first device, retrieve the identityId and password:
final String identityId = await qa.identityId;
final String? password = await qa.password;
copied to clipboard
Then in the second device, initialize the SDK with the identityId and password:
qa.init(
api_key: '',
identityId: identityId,
password:password
);
copied to clipboard
IMPORTANT NOTE: Since QuantActions does not have any connection with the user identity, data recovery in case of loss or damage of the device is not possible.
For this reason we suggest storing the QuantActions' identityId and password together with the user's account info.
In case of loss of damage of the device, the QuantActions SDK can be initialized on the new device with the user's
identityId and password which will restore the data and guarantee no interruptions of metrics between old and new device.

5. Setup notes: #

Check that you have added the api_key correctly where it ness to be added (Info.plist + .env file)
[Android] Check that you have requested the necessary permissions
[iOS] Check that you correctly added the keyboard and modified the Podfile

6. Checking that everything is running fine #
After the integration of the SDK has been done, you can add some checks to make sure everything is running fine.

You can check that the SDK has been initialized correctly by using qa.isDeviceRegistered() (returns a bool)
You can check that the data collection is running fine by using qa.isDataCollectionRunning() (returns a bool)
You can check that the device has been registered with the QA backend and/or the registration to a cohort was successful

qa.getSubscriptions();

7. Pausing data collection #
Although we do not recommend it, the data collection can be paused/resumed via the methods offered by QA singleton
qa.pauseDataCollection();
qa.resumeDataCollection();
copied to clipboard
8. Metrics and Trends retrieval #
While the data collection and synchronization is automated within the SDK. Retrieval of metrics and insights
has to be done manually within the app in order to access only the subset of metrics and trends that the application needs.
The metrics and trends can be retrieve programmatically in the following way (returns a Stream object):
qa.getMetric(metric: Metric.sleepScore, interval: MetricInterval.month),
qa.getMetric(metric: Trend.sleepScore, interval: MetricInterval.month),
qa.getMetric(metric: Metric.cognitiveFitness, interval: MetricInterval.month),
qa.getMetric(metric: Trend.cognitiveFitness, interval: MetricInterval.month),
copied to clipboard
Check Metric and Trend for the list of
metrics and trends available in the current version of the SDK, also check MetricInterval for the available intervals.
The function returns an asynchronous Flow containing a
TimeSeries object.
The test app accompanying the SDK has some examples on how to handle the return data.
Since the metrics for a user take from 2 to 7 days to be available (see ETA).
Developer can have access to sample metrics (that update every day) from a sampled device with
qa.getSampleMetric(api_key: api_key, metric: Metric.sleepScore, interval: MetricInterval.month);
copied to clipboard
Note that this method needs to be passed the api_key since it can be called without the need for the SDk to be initialized.
9. Journaling #
The SDK allows also to use a journaling function to log a series of entries. Each entry is composed of:

A date
A small text describing the entry
A list of events (from a predefined pool)
A rating (1 to 5) for each event in the entry

The predefined events can be retrieved with
qa.getJournalEventKinds();
copied to clipboard
With that adding (or editing) an entry is done by using
qa.saveJournalEntry(...);
copied to clipboard
Entries can also be deleted
qa.deleteJournalEntry(...);
copied to clipboard
The full journal (all entries) can be retrieved with
qa.getJournalEntries();
copied to clipboard
